    I bevieve this is the cause of my trans leak. Can I remove the accumulator with trans in the car? Any tips would be appreciated? Thanks in advance.

    If it is the accumulator under the VB or separator plate you should be able to, but I'm sure there are others with far more experience than myself. Look at YouTube 350 tear downs and see where in the sequence they get to the accumulator.

    What are the symptoms...other than a visible leak?

    DOH! I get it now you're talking about the accumulator on the side of the trans near the dipstick tube! That can be removed insitu although it is kinda cramped! There is a bolt hole above the accum "cap", to get the accum to compress put a thread in a bolt and use it as a pivot anchor for a bar and compress the accum. There should be a snap ring and/or a wick seal.

    Obviously the tricky part is getting the new seals well lubed and installed without nicking anything. Watch several vids on the method,and don't don't use grease to lube the seals.

It’s going to be hard working around the hedder and exhaust too. Haven’t watched any utube yet.

    It helps to push the cover in. To avoid damage, best way is to use a (large) glue clamp.

    Put some ATF on both the seals and the bore in the case.

    BPT catch more ATF than you would expect.

    Good idea about the clamp. I may have to buy a bigger one because I don’t think mine is big enough. I definitely plan on having a drain pan ready even though I took the plug out of my pan this past weekend. It is still dripping by the way.

    Just check the 'depth' it needs to fit over the pan. Most won't clear the pan/VB.

    We rolled the oring on mine and on the initial test drive it left an ATF stripe a foot wide all the way to the stop sign! Never leaked a drop until the car was moving. Paint in the butt to remove in the car but I got it done and sure enough, found a nick in the o-ring!
